Is it unsafe to take antibiotics (Doxycycline) for acne if I've been exposed to mold?

For the past 4 months I've been on two medications to control PCOS acne: Doxycycline and Spironolactone. I just found out that my house has mold and it's the reason that I've been having severe gastrointestinal issues (for the past two weeks) that I never had before. At first I attributed it to the Doxycycline, which is an antibiotic, as I've never been on a long term antibiotic and I assumed it did some damage to my gut bacteria. Now I believe it's the mold in my house which I've been exposed to long term. I stopped taking both meds. My skin has gotten horrible again. So my question is: is it safe to start the antibiotics again to try and clear my skin while I am detoxing from mold exposure and on the candida diet? I'm so confused!
